Like most everyone who was born after, say, the mid-70's, we're big fans of Super Mario—see figs. 1, 2, 3—so we're definitely digging Robert Bacon's "Super Mario New York City Subway" Map. As Andy Cush of Animal New York puts it, the poster is "perfect for the transit-obsessed gamer on your list."
Of course, we should also note that it's not the first example of an 8-bit Marioland remix of terra gothama: Jesse Eisemann's rendition, below, dates back to 2011 or so. New Yorkers, being the persnickety bunch that we are, will certainly find gripes with either version, but I suppose that's the beauty of the lossy, pixelated aesthetic: it conveys just the essentials, nothing more, nothing less.
